Preheat oven to 350 degrees F. Place your desired meat mixture in a large skillet. Add in the onions, peppers, and mushrooms. Cook over medium/high heat until brown. Stir in the diced tomatoes, tomato paste, dash of sugar, spices, garlic, and salt & pepper. Let simmer for 20-30 minutes.
Shred mozzarella cheese and set aside with cottage cheese.
In a 9x13 baking dish, put some of the sauce on bottom. Place 3 of the noodles (uncooked) on the bottom of the dish. Put a layer of cottage cheese, a sprinkle of mozzarella, and a layer of sauce; repeat layers.
Cover with aluminum foil and bake for 1 hour. Remove foil and check noodles, should be easily poked with a fork. Remove foil, top with remaining mozzarella cheese and let bake for another 5-10 minutes. Let stand for 10 minutes; serve.
